Monosodium Glutamate Monosodium Glutamate (MSG) is used in foods as a flavor enhancer while not providing their own separate flavor.Â Monosodium Glutamate (MSG) is considered an excitotoxin, a substance that overstimulates neurotransmitters in the body. The exitotoxic process plays a major role in many life-threatening maladies: strokes, brain injury, brain tumors, degenerative brain diseases (Alzheimer\'s, Parkinson\'s and Lou Gehrig\'s disease,) meningitis, neurological Lyme disease, encephalitis, schizophrenia, depression, bipolar disorder, addiction behaviors, multiple sclerosis and there is growing evidence that excitotoxins play a central role in autism.
